Appearance

Physically, Renge is identical to Kurenai, save for the small marks under her eyes. Renge is fairly tall and slim, as well as having a prominent bust. Her hair is light brown, like that of Kurenai's, however it tends to stick up a bit, like Kurei's does at times. Renge's clothing is also an exact copy of Kurei's, something he mocked her for.

Personality

Renge's mind is like that of a naive little girl, despite appearing to be a woman in her late teens. She follows Mori Koran's orders without question because she believes he is her father. Renge has little knowledge of right and wrong, and does as she's told to please her father. This is likely due to mental implants on Koran's orders to prevent her from growing out of control, like Kurei did. Renge is friendly to most she meets, but this does not mean she cares for their well being. Her mental state seems to deteriorate as time goes on and by the time she encounters Kurei, she seems to have become insane.

Ura Butou Satsujin Arc

Renge is not seen until the end of the tornament when Mori Koran ambushed Kurei, who was in a state of weakness and exhaustion after his battle with Recca. Renge impaled Kurei with her arrows of flame, and he was rescued by Neon.

Abilities

Renge is the successful result of a cloning project to duplicate Kurei's powers in the body of an obediant killing machine. Renge's primary power is firing arrows of flame, which she used to impale Kurei while he was in a weakened state. She was even able to fend off Hokage for a brief period of time. She could also fashion a blade of fire around her hand.
However, despite being fairly powerful, Renge's inexperienced mind is her greatest weakness. She has no knowledge of battle tactics and as stated by Kurei, she was far weaker than Recca. Also, possibly due to lack of understanding of Kurei's true power, her flame possesses no true form.
